Spring Strut / Channel nuts provide a secure anchor point in cable, tray and pipe support systems and other applications where are rectangular nut is required. Simply insert the nut into the trough of the channel, and twist into position so that the grooves are aligned with the internal edges of the strut. Threading and tightening a screw into the hole causes teeth located in the grooves to bite into the channel edge, positively locking the nut in place so it can’t slip
Suitable for: 21mm high channel
Other applications: Roof Racks, Aluminium Extrusions
Also known as: Channel Nuts, Strut Nuts
Material / Coating: Zinc Plated is the most common fastener of plating due to its low cost and shiny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically. It is intended to be used internally. Whilst some people use it externally it isn't recommended if corrosion is a concern. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel range
Thread Pitch (Metric): the distance between the peaks of two threads along a screw, bolt, nut, or fastener expressed in millimeters (mm). Used when referring to Metric parts. For example, a thread pitch of 1.50mm means that the distance between one thread and the next is 1.50mm
